SSI America BINARY SOLVENT DELIVERY MODULE 90-2581 REV B Manuel D’Utilisation

 

 A-7 

 

When activated (ENABLE IN is at a low logic level), the 

ENABLE IN input disables flowrate control on the front panel and 
enables flowrate control on the back panel. 

Special programming and circuitry allows this pump to be operated 

remotely with the flowrate controlled by voltage or frequency inputs.  
To select the remote mode of operation: 

 
a.)  With the pump plugged in and the rear panel power switch 

OFF, press in and hold the "DOWN ARROW" button while 
turning the power switch ON. 

b.)  Release the "DOWN ARROW" button and either a U (closest 

approximation to V for voltage) or an F (for frequency) will be 
displayed. 

c.)  Select the desired remote operating mode by pressing the 

"DOWN ARROW" button to toggle between the voltage and 
frequency mode. 

d.)  Press the "RUN/STOP" button to place the pump in normal 

operating mode. 

e.)  To enable the currently selected remote mode (voltage or 

frequency), connect the rear panel ENABLE IN connection to 
the COM connection. 

f.)  When in the remote mode (ENABLE IN at a low logic level) 

all front panel buttons remain active except the flow setting 
increase/decrease capability.
